很久之后,我下载了一个我共同开发的程序,并试图在我的 Ubuntu Linux 12.04 上重新编译它,但它似乎不再找到 math.h。这可能是因为最近发生了一些变化gcc
,但我无法确定它是否有问题src/Makefile.am
或缺少依赖项:
从http://www.ub.edu/softevol/variscan/下载:
tar xzf variscan-2.0.2.tar.gz
cd variscan-2.0.2/
make distclean
sh ./autogen.sh
make
我得到:[...]

这些库在那里是因为这个简单的示例运行良好:
$ gcc test.c -o test -lm
$ cat test.c
#include <stdio.h>
#include <math.h>
int main(void)
{
double x = 0.5;
double result = sqrt(x);
printf("The hyperbolic cosine of %lf is %lf\n", x, result);
return 0;
}
有任何想法吗?
